Revision total hip replacement: predictors of blood loss, transfusion requirements, and length of hospitalisation

Abstract

This study shows significantly greater blood loss in men, older patients, revision surgery of cemented implants, and dual-component revisions. More complex revision surgery and preoperative anemia are clearly associated with increased transfusion requirements and length of hospitalization. Identification and treatment of patients at higher risk of transfusion may guide likely transfusion requirements, shorten the length of hospitalization, and reduce the overall cost of treatment.
